Oil & Gas

Today’s concerns in the Oil & Gas industry are based on the following key performance indicators: safety, time to first oil, return on capital investment, production growth and production cost. Process Simulation is widely applied in the Oil & Gas industry to improve those KPIs. Inprocess has been supporting its clients by developing model-based applications or executing modelling projects.

With the objective of making production forecast for different future scenarios, without making physical shunting in the field, Inprocess' client required an integrated steady state simulation model.Client expects to later integrate the steady state pipeline model developed by Inprocess with a reservoir simulation model (already owned by client) in order to obtain an integrated simulation system which allows to study different production scenarios

A previously developed training system for a syster FPSO will be adapted to the operating conditions of current FPSO. New exercises, new procedures, other small scenarios were developed and incorporated into this new Process Trainer.Associated with the development of the tool, there were also operator training sessions, led by Inprocess instructors, at client site

Inprocess will develop three dynamic simulation models of the compression, produced water and sea water systems. Inprocess will detail the results obtained when testing the process control and protection devices by means of dynamic simulation.

Client requires inprocess to deliver process simulated on-site support and training for start-up operation based on Very Early Production Phase (150 MMSCFD) and production increase to Early Production Phase (300 MMSCFD) for the Venezuelan Field. Three on-site support and training stages with one inprocess’ process simulation expert working at Client premises in Venezuela will also take place.

Flow Assurance Study based on the dynamic simulation to evaluate and identify the various problems that can be faced during start-up, shutdown, pigging operations for selected gathering system trunk lines and transfer lines of the Algerian Oil Field using OLGA Software.

The project’s main objective was to develop pipeline simulation models with OLGA® in order to:- Perform WHT topside depressurization and report minimum metal temperature andconfirm it is within MMDT, fluid temperature at restriction orifice (RO) inlet & outlet,depressurization rate and depressurization time for WHTs topside well fluid and gas liftfacilities.- Identifying all possible cases for hydrate formation and provide recommendation formitigation measures to prevent the hydrate formation for all the cases.- Identifying the depressurization and hydrate formation cases of well fluid, gas lift and excess gas.

Through a series of dynamic simulation studies carried out by Inprocess our client will verify the equipment suitability for defined design cases of the floating production unit, inluding compressors, drivers, pumps, heat exchangers and columns performances. It will also evaluate the control valve sizing, the primary and secondary protection systems and the instrument ranges and alarms. In addition, the engineering model shall be used for control system design studies including Compressor surge protection, Control strategies, Controllers tuning, Shutdown philosophy and sequences (including PSD- and ESD) and Complex control sequences and procedures. Finally, the engineering studies cover operability studies in addition to verification of operational procedures.
